What is Leptin
Many people believe calorie intake, together with exercise and your ability to stop eating before you are stuffed determines whether you gain or lose weight. However recent research on obesity has indicated that a hormone called leptin has a critical role in weight gain and or loss.
A hormone which affects just about everything that takes place in your body, Leptin is secreted by your white adipose tissue, a fat found in the abdomen, thighs and buttocks.
How Does Leptin Work
Leptin is also known as the satiety hormone. It tells the brain when there is adequate fat stored, that we do not need to eat anymore, and that our bodies should burn energy normally. Low leptin levels were a signal to the brain to store fat to an adequate amount for survival. Today, we do not have a food shortage problem, our problem is food everywhere.
The long term function of leptin is to regulate the amount of calories we eat and burn through our activities and the amount that is stored as fat in our bodies
When leptin is secreted from the fat cells it travels via the blood to the brain to let the brain know that you are full and the brain then lets you know that you are full. This works when there is not a leptin imbalance. If there is an imbalance your brain does not get the correct signal and you continue eating often overeating leading to obesity. This condition is called leptin resistance. Because the brain did not receive the correct signal to say that you are satisfied
Fat cells produce leptin based on their size. Obese people therefore have more leptin. If the hormone worked as it should a signal should go to the brain advising that there is an adequate supply of fat stored. However since there is a malfunction of the hormone the brain does not receive the correct message of satiety and the obese person continues to eat. This condition is called insulin resistance
When the brain receives the wrong leptin message it thinks the body is starving even though there is more than adequate fat stored. The brain then sends signals tht are erroneous causing our body to change its bodily processes and behaviour to regain the fat that the brain thinks the body is lacking. It therefore sends signals to eat more and expend less energy.
Therefore dieting may be one of the causes of leptin resistance. When you diet your leptin levels decrease and the body fights to restore the stored fat.
Weight loss is often a struggle and many who strive to lose weight do not enjoy long term success
There might be many reasons why you are not losing the weight but based on research leptin may play a role
